摘　　要：铁路油槽车上部卸油易产生气阻,尤其是在炎热的夏季卸汽油时,气阻问题更为严重。为提高抗气阻的能力,使铁路卸油更为顺畅,提出了3种新型铁路卸油工艺:潜油泵卸油法、滑片泵卸油法和滑片泵离心泵结合卸油法。Air blocking phenomena are likely to appear at the upper end of the rail tankers during the unloading process,especially in hot summer.To solve the problem and make unloading smoothly,three new technologies are introduced:unloading by submerged pump,by vane pump or by both.
